Exclusive-Alleged Israeli Spy Company Heavily Targeted Starlink Users, Sources Say

Researchers said the ad-tech firm was the top bidder on Starlink traffic in more than 100 countries and may have used ads to track users.

  • TrendAI, a unit of Tokyo-based cybersecurity company Trend Micro, found that Israeli ad tech firm Discover-Tech heavily targeted users of SpaceX's Starlink satellite service, becoming the No. 1 bidder on Starlink traffic in more than 100 countries.
  • Because Starlink terminals sidestep local internet restrictions and communicate across battlefields, tracking them has become a 'cottage industry' for governments worldwide, prompting suspicious bidding patterns by an entity TrendAI codenamed Shadow-Earth-79.
  • Canadian cyber watchdog Citizen Lab and New York advertising technology firm Confiant separately identified Discover-Tech, alleging the company abused the ad bidding process to de-anonymize users across sensitive networks belonging to media organizations, governments, and tech firms.
  • In response to investigations, Google, Comcast, and other companies removed Discover-Tech from their advertising platforms, while the firm and its CEO did not respond to requests for comment over the past two weeks.
  • Reflecting broader industry trends, TrendAI initially avoided naming the firm to prevent 'hype-driven labels,' citing concern that unstable actor names can mislead defenders and trigger inappropriate response actions.
